A former brothel owner gets impregnated by an animalistic client during a drug-fueled sex binge, and gives birth to a mutated infant with a hunger for human flesh. Upon discovering she will soon become a mother, Rachel "Madam" Won Ton quits the prostitution racket, and prepares to settle down. But later, when surgeons attempt to remove her developing daughter's parasitic twin in utero, the evil fetus springs to life, and sets out on a gore-soaked rampage. Gunnar Hansen and Debbie Rochon star.
